IIRC, aren't the dive brakes missing from the G model?
The dive brakes don't work well on the D-3 now anyway. Something about diving 5k with an 1800kg bomb strapped to the bottom of the plane makes the dive brakes worthless.

I generally just trim the peepee out of it, kill my speed to a nose up stall, tip it nose down and let'er rip.
How difficult would it be to add the gun pods in the hangar as a separate loadout that doesn't allow any other additions and have the flight characteristics automatically adjust to the the correct properties? Or would it just be easier to build a whole new model off the existing Stuka?
